...me I looked at my mmiotraces, these seem to be all valid registers. Forwarding this to stable, as there's a small chance that not having these could cause clockgating to be unstable.

...f100_clkgate_init() to actually write registers! This got broken in the last version by accident - Dump the register packs and the resulting register writes into nvkm_trace() in gf100_clkgate_init() so we can make sure this doesn't happen again And some more minor changes: - Make all SLCG/BLCG mmiopacks for kepler2 static Additionally, I just discovered that these patches have a higher chance of crashing your card if you reclock under load. However, reclocking under load has never been supported by nouveau in the first place and has always caused trouble so that's nothing new :...

Next version of my patchseries for adding clockgating support for kepler1 and 2 on nouveau. The first version of this series can be found here: https://patchwork.freedesktop.org/series/36504/ Some minor changes: - Clarified that SLCG stands for 'secondary level clockgating', thanks for the small tip nvidia! - Removed the concept of levels, this was more useful for debugging then anything and having only a single level of clockgating enabled does technically open us up to running a configuration nvidia never...
